Namespace:   System.Diagnostics.Contracts.Internal
Assembly:  mscorlib (in mscorlib.dll)

public static string RaiseContractFailedEvent(
	ContractFailureKind failureKind,
	string userMessage,
	string conditionText,
	Exception innerException
)

Parameters

failureKind
Type: System.Diagnostics.Contracts.ContractFailureKind

The type of failure.

userMessage
Type: System.String

Additional user information.

conditionText
Type: System.String

The description of the condition that caused the failure.

innerException
Type: System.Exception

The inner exception that caused the current exception.

Return Value

Type: System.String

A null reference (Nothing in Visual Basic) if the event was handled and should not trigger a failure; otherwise, returns the localized failure message.

Exception Condition
ArgumentException

failureKind is not a valid ContractFailureKind value.

The binary rewriter calls this method to notify listeners about a contract failure. The RaiseContractFailedEvent method does not perform the failure behavior (an assert or throw) itself. If the failure is handled by the listeners, the method returns null. If the failure is not handled by the listeners, a localized failure message is returned.
